To all whom it may concern:

Be it known that l, LOUIS FilLIZAT, citi zen of France, of Bouches du-Rhone, France, have invented a new and useful Improvement in Apparatus for Making Wood-Chan coal, which invention is fully set forth in the following specification.

This invention relates to improvements in apparatus for making charcoal and more particularly to the production of charcoal from ground ligneous materials such es elm'ond shells, peach or apricot kernels, olive husks, sawdust and the like smiths invention has for its principal object to not only produce a charcoal of superior quality, but to utilize the heat of combustion of the vaporous and gaseous products resulting in the cerbonizing operation particularly for' the production of steam.

The ordinary pile or lieu-p process of making' charcoal is lengthy and uncertain as.

to output and the quality of the product,

It is not unusuahto burn under boilers industrial refuse such as Waste products of oil factories and other iigneous Waste products for the purpose of raising steam. In view, however, of the extreme divisibility and slight density of such products, combined with the fact that they contain a comparatively large quantity of volatile substances, it is not practical to realize the full calorific power of such Waste burnt in this manner.

This application is a division of my coending application, Serial No. 545,897

filed February 25, 1910, which describes and claims the process herein disclosed but not clsimedfl This process briefly stated consists in introducing, preferably by showering, the comminuted Waste ligneous materials into a, furnace heated to redness While introducing at thesame time iii! to effect the complete combustion of the volatile products which are dissociated from the waste and which ignite on coming in. contact with the red hot Walls of the chamber. The residue remains on the bottom of the chamber in the form of incandescent charcoal. The hot gases are conducted under boilers to raise steam and thereby utilize the calorific One constructional form o 1e :ippsmtus NEIL-114m Divided and this spcllcsticn sled July 21.

embodying my improvements is illustrated in the accompanying drawings in Which-- Figure l is a view peril}; diagrammatic partly in section showing in combination the elements of my apparatus, and Fig. 2 is s View partly diagrammatic and partly in central vertical section through one oii' the furnaces. I i

As shown in the drawings, the furnace 2 is divided into two heating chambers 1 1 separated by a fire brick partition. The chambers l, 3. open through. outlets 3, 3, controlled by doors 3 3" into line 4- which conducts the hot products of combustion under the boiler, not shown. Escher these furnace chambers has a firs brick hearth 5 sloping toward the discharging door 6 or The charging is done in the following manner: A hopper '5" into which the products to be burned are dumped directs them onto an endless distribut is screw arranged before the battery of iurnuccs. lit the height of each furnace, an endle s screw 9 disposed at right angles to endle 3 screw 8 c' onducts the product to charred into the ventilator conduit 9' which is provided with a fan 10 turning at eight to twelve hundred revolutions per minute according to the nature of the product. From this conduit the product is projected in s. shower into the upper part of the furnace cnsmber andislls onto every part of the bottom of the furnace. The combustible as soon as it enters the fun nace liberates all its volatile portion which inflanies in contact with the red hot walls of the furnace and in presence of the air intr duced with the combustible The residue falls to the bottom in the form of incandescent charcoalwhile the products of combustion are discharged through. the flue 3. The hopper '4" is provided'with a. register 11 just above the screw 9 for the purpose of regunice Willis and the residue remains on the hearth 1n the ionic. of incandescent charcoal ice j i lie protectedfrom further combustion by theinsulficient supply. About every three hours the charcoal lying on. the hearth is removed through the doors 6 end 6 and thrown into a small truck 7 where it is sn'zothered or quenched. To insure the proper Working of the boiler, the furnaces 1 and l are emptied alternately so that one shall always be inaction. By this means it possible to utilize residues ofthe kind in question in much more economical manner then heretofore so long as they are of a. combustible neture. Thus for instance thewhole of the volatile products Without exception on. coming into contact with thercd hot nulls of the furnaces become ignited and bin-n in a complete manner; moreover it is practicable by thismeuns to burn with excellent results certain residues which are so pulverized or charged with Water that it would be almost impossible to burn them on,

fire grates. I

The residue of wood charcoal obtained by commercial value superior to that of the combustible bu nt. Thus, taking us an ex- ;miple a' steam boiler burning with ordinary grates 1000 kilos of ground nut shells, for instance, Worth about sixty cents, only. about 800 kilos of the shells would require to be burned with the process forming the subjectunatter of this application for the same quantity of Water evaporated in the boiler, but besides this-there would be obtained as residues 220 kilos of charcoal W orth $1.60 to $2.00. As the residues hereinbefore referred to yield from 22 to 28% of their Weight of wood chrurcoal, this means of production hecomcs of great interest at :1. time when wood charcoal is becoming rarer and rarer not- Withstandin its low cost price- What is c aimed is:

1. In a. furnace for making charcoal iron. residues of ligneous materials, the combine.-

. tion of e oerbonizing chumhe an inlet 0onresidues of ligneous materials comprising a carbonizing chamber having a, charging inlet above the churcoal level and a discharge opening substantially opposite said inlet, and means for showering the ligneous materials through said inlet into the zone of pertiul combustion in the upper purl; of the chamber and onto the furnace hearth.
